Abstract
Improving Internet service performance is essential for the future wireless networks. The correlated fading channels are found very unfriendly to TCP performance in such networks. Moreover, the variation in fading rate brings further challenge to wireless networks when supporting Internet applications, most of which runs TCP as the transport layer protocol. In this paper, we first analytically study the performance of different RLP (Radio Link Protocol) retransmission schemes in supporting TCP. An analytic metric called RLP retransmission efficiency is introduced to evaluate performance of different RLP retransmission schemes under correlated fading channels. With analytic and simulation results, we show that a single retransmission scheme does not yield the best performance over different rates of fading. Based on this observation, we propose an Adaptive Radio Link Protocol (ARLP) that has a fading rate detector to estimate the channel fading rate. Based on the estimated channel fading rate, ARLP adaptively adjusts its retransmission schemes to achieve the optimal data transmission performance. Simulation results show that ARLP can improve both the performance of a particular mobile host and the total throughput of wireless networks.
